Description / Features

Compared to other techniques, RoKCell allows an analytical inversion of four of Johnson-Champoux-Allard-Lafarge's model parameters. It also provides asymptotic estimations of 2 more parameters for this model.

To date, RoKCell is the only analytical tool which allows a characterization of the static thermal permeability introduced by Lafarge et al. [LLAT97]

RoKCell main features are :

Below, a 6-min video shows an example of the acoustic characterization of a foam using RokCell.

Here are some screenshots of RoKCell main panel and RoKCell characterization windows for visco-inertial (tortuosity, viscous characteristic length) and thermal parameters (thermal characteristic length, static thermal permeability).
